Will they break if frozen (for frozen drinks)?

I don't think they will break if frozen because they seem to be substantial and pliable enough to withstand freeze, but I have not tested them. I have been very pleased with how well they are holding up after several dishwasher cycles. Still look and feel brand new.

I probably would not freeze them. They are pretty thin and don't appear to be designed for the freezer. They have a similar thickness to a wine glass at the top.

Extremely strong glass. Very thick. I would think if you left room for some expansion of frozen liquid, they should be fine. I have not tried freezing anything in them. This is only my opinion based on how sturdy they are.

I haven't but I'm sure you can. I just wouldn't leave them frozen for an extended period. I love these for many different uses.

I would say they are sturdy enough for frozen ice cream. I did detect an aftertaste in the metal.

I don't know about long term freezing, but the most popular recipe (on the back of the box) calls for a frozen "log" of wafers and whipped cream, and it is all frozen. So, short term, they should be fine. The real problem is that big, thin wafers may break. It doesn't seem to matter, though, since it is only a few.

Yes! I have placed them in the freezer many times, no cracks or wear signs!

I'm not sure about freezing. I'd think you could but they have a 6 month shelf life :)

Yes! They won't fit nicely into each other like regular ice cube trays, but once frozen you can stack them.

Not sure it can be frozen but I would imagine it could be. I do know they are good for a year to use. Hope this helps. :)

I have not tried to freeze them. And I don't think it would work very well. If the expanding liquid didn't break them, the extreme cold would probably make them more prone to crack

If they are already frozen, I don't see why not. They would, however, be open at the bottom. Just my opinion, though.

I've had one of them break but not like you described. The end of one of them cracked when the cup got knocked over. No problems so far with screwing the lid on even when my cup was filled with lots of ice.

I've never tried to freeze them, but they are dishwasher safe so I would assume that means they are able to be frozen. They don't expand like a throw away bottle would so you would just have to be careful to leave room for the liquid to expand.

sorry...I have never tried freezing them but they are awesome for regular use.

No. The bowls did not break. The motor broke the first time I used it. The bowls were in the freezer for a good two weeks, they are / were undamaged.

I'm not sure if they are freezer safe, I haven't had mine for very long and the tabs have already broke off. The only thing that I could see being an issue would be making the plastic more brittle and break more easily.
